DXi Wireless Output Board (WMS only)
Installation and Setup Guide
Selecting the Controller Installation Site
The DXi wall-mount cabinet is designed for indoor or outdoor environments. Selecting an installation site that provides
user accessibility as well as basic protection from extreme hot or cold environments is considered good installation practice.
At minimum, the installation site should provide the following:
• Protection from direct exposure to irrigation spray, midday sun, and snow accumulation.
• Access to all required wiring connections.
• Access to a dedicated, single-phase AC power source.
• Line of sight from the DXi controller, especially by metal walls or obstructions.
Installing the Wallmount Enclosure
1. Unlock and open the cabinet door, then open the hinged
control panel. Position the controller on the wall at eye level,
and mark the top and bottom mounting screw locations.
See Figure 1.
Note: Two stainless steel screws are provided for installation to a
wall stud. If installing the controller on masonry or drywall, use
the appropriate type screw anchors and fasteners.
2. Install the screw anchors at 8¾” (22,23cm) (A) on center.
!
Caution: All cabinet openings required for installation
and wiring are provided. Drilling or cutting through the
cabinet should be avoided. Metal chips and filings entering
the cabinet can damage internal components.
3. Install the top mounting screw (B) leaving a ¼” (6,4mm) gap
between the screw head and wall.
4. Hang the controller on the mounting screw, ensuring the screw
is located at the top of the cabinet keyhole slot. Install the lower
mounting screw (C), then tighten both screws securely.
Installing the Electrical Conduit
1. Remove wiring terminal block cover (1).
Install electrical conduit from the power
source circuit breaker panel to the controller
location. Attach conduit to bottom of
cabinet using the ½” / ¾” (13mm / 19mm)
access opening (2).
2. For field wiring, attach 2” or 3” (51mm
or 76mm) conduit to cabinet using center
access hole (3).
3. An additional ½” / ¾” (13mm / 19mm)
access hole (4) is provided or auxiliary
wiring.

Figure 3

Connecting an Earth Ground
!
IMPORTANT! e DXi controller surge
protection components cannot properly function unless
an ecient pathway to earth ground is provided. e
ground path must be as direct as possible, without sharp
bends and must not exceed 10 Ohm resistance (when
measured with an earth ground resistance device). All
electrical components throughout the irrigation system
should be grounded similarly to provide the same
ground potential.
e following instructions depict one of several
acceptable earth grounding methods. Due to variables
in soil composition and terrain, the method shown may
not be suitable for your installation site. Contact your
local Toro distributor for assistance and availability of
the required earth ground resistance test instrument.
Recommended ground testers are: AEMC Instruments,
model 3710 clamp-on tester, or Biddle Megger, model
250260 (or equivalent).
Steps
1. Drive a 5/8” by 10’ (17mm x 3m) copper-clad steel
rod into well-moistened soil, not less than 10’ (3 m)
or more than 12’ (3.7 m) from the controller. e top
of the ground rod should be buried approximately
12” (30.5cm) below grade.
2. Route a 6 AWG (13,0mm2 ) solid copper wire
connected to the earth ground device into the
controller cabinet through the access hole provided
below the copper ground lug. Insert and secure the
copper wire to the ground lug. To provide the most
ecient path to earth ground, route the ground wire
between the ground rod and controller with the least
amount of bending possible. ere should be no tight
radius bends, nicks, or deep scratches the entire length
of the wire.
3. For optimum connectivity, secure the ground wire to
the ground rod using a Cad-WeldTM (or equivalent)
metal-fusion connection method.
4. Using an earth-ground resistance tester; i.e., Meggor®
or equivalent, conrm the resistance reading between
the controller and ground rod is 10 ohms or less.
Contact your local Toro distributor for assistance in
obtaining the earth ground-resistance test device.
Periodically retest the earth ground connection to
conrm that resistance remains at 10 ohms or less.

Connecting Field Wiring
!
Caution: The DXi WOB transformer is rated at 24 VAC, 50 VA. Each station output terminal is rated 24 VAC,
0.5A (max.) @ 77°F (25°C), and capable of operating more than one valve solenoid (typically 2 or 3).*
Ensure the current load on any output does not exceed 0.5A.
Ensure the total current load imposed on the controller
does not exceed 1.75A.
* The irrigation system hydraulic capacity must be also be capable
of maintaining adequate volume and pressure for all automatic and
manual watering operations.
To provide a field common wire, attach one wire to either solenoid
lead of all valves to be operated by the controller.
Attach a separate power wire to each remaining solenoid lead.
Label these wires for identification at the station output modules.
Use an approved waterproof splicing method to properly insulate
all valve solenoid wire connections.
Connecting Station Valves
The DXi features up to 48 direct-insertion, quick-release wire
terminals for all low-voltage wire connections. Each field output
terminal accepts a 14–18 AWG (2,08mm2 – 0,823mm2) solid-
core wire in each of two connection ports – enabling two field
wires to be connected independently to one terminal position.
Steps
1. Route the field wires into the controller cabinet through 2”
(50mm) conduit.
2. Remove approximately 3/8” (10mm) insulation from the ends
of each wire.
3. Connect the valve common wire(s) to terminal marked
“VC / COM” .
4. Connect each valve power wire to the appropriate station number terminal. See Figure 5.
5. Pull lightly on each wire to confirm positive retention.
6. Ensure all exposed wiring inside the controller is taped back and properly insulated.
7. To release, depress the small tab (nearest the wire) using a small blade screwdriver.
Output Switch Operation
e 3-position switches provided on the station output module
(Figure 6) enables local control of the station and master valve output.
e switch positions are as follows:
ON – Manually activates the terminal. e terminal will remain on
until the switch is moved to the AUTO or OFF position. An indicator
LED will illuminate when the switch is on the ON position.
OFF – Shuts o the terminal. e terminal will be inoperative (for
both automatic and manual operation) while the switch is in the OFF
position.
AUTO – Enables the terminal to be automatically controlled during
automatic or manual operation.
!
Caution: To prevent controller damage, do not operate more
than six stations concurrently (1.75A total load maximum)
during either manual or automatic operation.

Connecting a Pump Control
!
Caution: Do not be connect the controller directly to the pump motor or starter. A 24 VAC isolation relay; i.e.,
Irritrol SR-1 Pump Start Relay (or equivalent), must be used to facilitate the pump control circuit connection.
1. Install a 24 VAC pump start or
equivalent isolation relay. Route
and connect a control wire and
a common wire from the Pump
terminal of the Pump/Master Valve
terminal block to the relay. See
Figure 7.
2. Connect the remaining pump
wiring per the instructions
provided by the pump equipment
manufacturer.
!
Caution: If multiple
controllers are utilized within
the irrigation system, do not
interconnect the controllers’
field common, pump or
master valve wires. Damage to
the controllers can result.
Note: Contact technical support
at 1-800-777-1477 for information
regarding multiple-controller wire
connections.
Connecting Sensors
The DXi controller provides connection terminals for two flow sensors at the bottom of the WOB. One terminal is
marked FLOW1, the other FLOW2 (see Figure 8).
!
Caution: To prevent damage to the controller and/or sensor equipment,
turn off power to the controller prior to connecting sensor wires.
Installation Notes:
• The ALARM terminal is
not used.
• The sensor connection
terminals accept 16–28
AWG (1,5mm2–0,08mm2)
solid-core copper wire.
To enable positive wire
retention, insulation must
be removed from the end of
each wire to expose ⅜ –½”
(10–13mm) bare copper
wire.
• Flow sensor wires have
specific polarity that must
be maintained for proper
operation of these devices.
Note the GND indicators
on each sensor connection
terminal and connect
accordingly.

You are now ready to “train” the Wireless Output Board to communicate with the DXi Timer Module.
1. From the DXi controller Main menu, select Stations

Main Menu WED 5:43:40 PM
.
2. Press RT button to navigate to the Type screen.
3. Complete the following:
• Type: Select Wireless LR.
• Precode: Set to the precode the WOB is trained to (000-999).
Typically this is set to the same as the unit code of the controller.
• Board # (0-30) – is corresponds to the position of the rotary
switch on the WOB (see Figure 9).
Note: Switch positions labelled A = 10, B=11, C=12, D=13,
E=14, and F = 15
• Output # (1-48) is corresponds to the output terminal desired on the WOB.
After communication is setup, the WOBs can be trained. Put the WOB in Training Mode by pressing, pausing, and
releasing the Learn/Test button on the WOB. e board’s LED will begin ashing. If you press the button a second time,
the board will self test, running each output for about 1 second. Wait for the test to complete before retrying to enter
Training Mode OR reset the WOB by power cycling the controller.
Figure 9 below shows the top portion of an AC WOB (with radio module removed).
Note the Learn / Test button and the 16-position board address switch.
Once a board is in Training Mode, the next WOB communication it detects will cause the precode in the
communication to be “learned” so that, from that point forward, the board will only listen to communications with
that precode. is allows multiple DXi controllers to run WOBs with the same board numbers within radio range since
each WOB only listens to the precode of its master.
Once a board is in Training Mode, send a communication from the DXi TM by turning on any wireless output. All boards
in Training Mode will learn the precode and stop ashing the LED. Make sure the switch is in the AUTO position. e
output you turned on will turn on and the LED will light on the designated WOB, but all boards in Training Mode will
have learned the precode.
• Test communications with each WOB by turning on an output on that board from the DXi controller.
• Now that the WOBs have learned the precodes, it is possible to use Command Interpreter Mode to set ow parameters
in each WOB as well as check ow readings from individual WOBs.
• In Command Interpreter Mode, address each board using its precode (aaaaa below) and its board address (bb below).

Command Interpreter (send radio commands to a specic WOB):
• Used to set ow mode parameters on WOB and for general testing of communications and ow.
• To send a command to a board, connect XTEND serial radio to laptop, and launch a terminal program (hypertrm is
installed Windows XP). Set to 19200 baud with no ow control (19200 N81). You may nd it easier to create a .txt le
with the desired commands, and then use hypertrm Transfer menu -> Send text File to send the commands to the radio.
It is also possible to type commands directly into hypertrm but note that a delay between characters or commands will
cause the command to fail.
All commands Start with ATaaaaabb where:
aaaaa is the board precode (typically 00 followed by the three digit address of the master unit)
bb is the board number on the address switch. ( A=10,B=11,C=12,D=13,E=14, and F = 15 )
To test communication:
Send: ATaaaaabb Response: aaaaa:bb->WOB ver:0.51 (or current version)
To read k factor:
Send: ATaaaaabbKc?
(where c is the ow input number (1, or 2)
Response: aaaaa:bb->Kc = <K setting here>
To set k factor:
Send: ATaaaaabbKc=ddd.ddd
(where ddd.ddd is desired k factor
padded with zeros)
Response: aaaaa:bb->Kc Set
To read oset:
Send: ATaaaaabbOc? Response: aaaaa:bb->Kc = <oset setting here>
To set positive oset:
Send: ATaaaaabbOc=e.eee
(where e.eee is oset factor
padded with zeros)
Response: aaaaa:bb->Oc Set
To set negative oset:
Send: ATaaaaabbOc=-e.eee
(where e.eee is oset factor padded with zeros)
Response: aaaaa:bb->Oc Set
To read ow mode:
Send: ATaaaaabbM? Response: aaaaa:bb-> <ow mode 1+2 or 1-2 will be indicated here>
To set ow mode:
Send: ATaaaaabbM=f
(where f = 0 for additive (1+2) or
f = 1 for dierence (1-2)
Response: aaaaa:bb->Flow Mode Set
To read ow data:
Send: ATaaaaabbF? Response: <several lines of ow data showing channel 1, channel 2,
and combined results>
